Drainage system



June 23, 1931. s. A. HARTMANN DRAINAGE SYSTEM Filed Jan. '7. 1930 AHomey Patented June 23, 1931 UNITED STAT SAMUEL A. HARTMANN, OF JACKSON,MISSOURI DRAINAGE SYSTEM Application led January 7, 1930. Serial No.419,090.

This invention appertains to new and useful improvements for drainagesystems for buildings, and the same has as its principal object,provision whereby circulating waters may be trapped beneath a buildingand drained off to a sewer or some other remote point.

Another important obj ect of the invention is to provide a drainagesystem which after '10 being installed will not require furtheratbuilding showing the ditches layed off andV filled with suitablecoarse granular material through which water may easily seep.

sectional View substantially on line 2 2 of Figure 1.

Referring to the drawings, wherein like numerals designate like parts,it can be seen in Figure 2, that the numeral 5 represents the footing orfoundation for the walll 6, this being all of the building disclosed inthe drawings. f

In carrying out the present system, a vertical bore 8 is made toterminate at a level beneath the footing 5 and at spaced intervalsoutside of the confining area of the footing 5. Whether a ditch is dugstraight downwardly or the work is consummated by tunnelling, isimmaterial in providing the inwardly disposed ducts 9 which communicatethe lower ends of the bores 8 with the ditch 10.

This ditch 10 extends in close proximity to the inner side of a buildingwall 6 and beneath the bottom level of the footing 5, as in the mannershown in Figure 2. A diagonally disposed ditch 11 connects one corner ofthe ditch 10 with the diametrically opposite corner and in this lastmentioned corner a drain Figure 2 represents a fragmentary verticalopening 12 is provided for communicating the ditch 10 with a drain pipe13.

The ditches 10 and 11, and the ducts 9V are filled with some suitablecoarse granular material such as crushed rock or gravel and asV shown inFigure 2, the bores 8 are filled to the level 14 with this material, andfrom there upwardly with earth.

The concrete or cement floor or covering 15 is then laid over the entirearea withinthe confines of the footing 5. It will now be seen that anywater percolating through the ground beyond the side walls of thebuilding will eyentually form fissures leading to the ducts 9 and whenwater has gained this point, the same will readily sift through thegranular material and ultimately pass into the drain pipe 13.

Thus the walls and iioo'ring 15 will be maintained constantly dry by thenovel system of drainage.

Obviously certain variances of the system may be resorted to toaccommodate various shaped structures without departing from 'the spiritand scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

The combination with a building including foundation walls and a bottomfloor, of drainage means for the building comprising ditches arrangedbelow the walls and floor and within the Vconfinesof the wall andfollowing the outline thereof, a diagonal ditch connecting the cornersof the first ditch together at opposite points, a drain'pipe connectedwith the first ditch, and lateral ditches connected with the first ditchand extending' below and beyond the foundation walls.

In testimony whereof I affix my signature.

SAMUEL A. HARTMANN.
